BACKGROUND OF THE INVENTION

(a) Field of the Invention

The present invention relates to a thread structure of an aerator of a faucet water outlet, with the design of the pitch, the major diameter and the pitch diameter of an internal tread of the aerator and the variation tolerance, an effective engagement relation can be established when subject to the different metric and imperial specifications of the external thread of a faucet water outlet. As such, the present invention provides a universal utilization and application.

(b) Description of Related Art

For avoiding an issue of water splashing while controlling the flow amount of discharged water from an faucet, an aerator is often installed in the water outlet part, thereby obtaining smoother water flow and preventing water splashing, so when a user allows the water to be discharged in a massive amount, the surroundings is prevented from being splashed with water and being wet.

What shall be addressed is that after the mentioned aerator has been used for a period of time, problems such as blocking or permeating may occur, so the aerator is seen as a consuming product which has to be replaced every now and then. For facilitating the detachment and engagement of aerator, the manufacturer often has the bottom end of the faucet water outlet to be designed in external thread, and the aerator is designed in internal thread. With the matching design of internal and external threads, the aerator and the faucet outer outlet can be smoothly and effectively engaged and locked.

However, in the faucet production, the measurement system and custom in different market regions may adopt different specifications, such as metric and imperial; i.e. for the matching of the threads of the faucet water outlet and the aerator, two different specifications of metric and imperial are therefore generated. As a result, a metric aerator cannot be used with an imperial faucet, and an imperial aerator cannot be used with a metric faucet, and a forced engagement of different specifications may cause inadequate engagement and permeation. Thus for the sales of aerator, the aerator is clearly marked with the specification of faucet suitably to be applied, thereby preventing the consumer from buying the unsuitable aerator.

As a matter of fact, most consumers is not aware of the faucets that they have been used are in metric or imperial measurement, or do not have the knowledge of identifying the specification of the faucet they are using, so when buying an aerator, they would not pay the attention to which is the suitable specification, and often feel frustrated when being aware that the specification is wrong and the purchased product can be not used. In addition, there is another problem related to the lack of specification knowledge, when the consumer take the product back to the shop for replacing the one with right specification, the free replacement may not be carried out because the package material of the product is damaged or not complete, or the product has some scratches, so extra money has to be paid for getting the right product. As such, not only the money may unnecessarily pay out, extra time and other inconvenience may also happen.

SUMMARY OF THE INVENTION

In view of the problems and disadvantages related to the thread engagement of existed faucet water outlet and aerator, the inventor of the present invention has been devoted himself in relative industries for many years and have advanced skills and acknowledge to make an integral design for the metric and imperial thread structures of the faucet and aerator which are commonly seen in the marketplace, therefore an improved structure is provided, in which the specification of the external and internal thread of an aerator is designed to be capable of being engaged and locked with a metric and an imperial internal thread of faucet water outlets having the same specification, and also capable of being engaged and locked with a metric and an imperial external thread of faucet water outlets having the same specification, thereby achieving the practicability and convenience of being universally applicable to both of the metric/imperial internal/external thread of faucet water outlet having the same specification.
